Targets:
    local:              - build locally
    all                 - build normal and xen kernel for 2.6 (default rule)
      kernel              - build normal kernel for 2.6
      smp-kernel
    check	        - check generated kernel against files.txt
      check-kernel        - check normal kernel
      check-smp-kernel
    update	        - update generated kernel against files.txt

      update-smp-kernel

Commandline Parameters:
    REPO  - repository location for check and update (default: /home/fli4l/test-fli4l-trunk)
    KERNEL_DIR - target and working directory 
    FORCE - update accepts a -f to update the repository immediatly

Examples:
    make
    make check REPO=path_to_repo
    make update FORCE=-f
    make kernel KERNEL_DIR=path_to_target_dir REPO=path_to_repo
